Introduction
This document defines the requirements which can be called up for joints, stop ends, separable connectors,
indoor and outdoor terminations when used with impregnated paper insulated power cables covered by
HD 621. The equivalent requirements for extruded power cables are given in HD 629.1 S3.
The equivalent requirements for transition joints, when used between extruded insulated power cables and
impregnated paper insulated power cables covered by HD 620 and HD 621 or other relevant standards are
given in HD 629.3 S1.
Formerly, approvals of such products have been achieved on the basis of national standards and specifications
and/or the demonstration of satisfactory service performance. The publication of this document does not
invalidate existing approvals. However, products approved to such earlier standards or specifications cannot
claim approval to this document unless specifically tested to it.
1 Scope
1.1 General
This document specifies performance requirements for type tests for cable accessories for use on impregnated
paper insulated power cables as specified in HD 621.
It is not necessary to repeat these tests, once successfully completed, unless changes are made in the
materials, design or manufacturing process, which might affect the performance characteristics.
Accessories for special applications such as submarine cables, ships cables or hazardous situations (explosive
environments, fire resistant cables or seismic conditions) are not included.
Test methods are included in EN 61442:2005.
NOTE It might be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity
assessment body, to demonstrate that conf
